TELEPHONE-GUARD.

SPECIFICATION forming part of Letters Patent No. 644,680, dated March 6, 1900.

Application filed December 12, 1898. fierial No. 699,101. (No model.)

To all whom it may concern.-

Be it known that I, LILLIAN B. ORDWAY, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented certain new and useful Improvements in Telephone- Guards; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a telephone-guard which shall not only prevent foreign matter from entering thelmouthpiece of a telephone, but shall resist accumulation on the surface of the guard of all foreign matter and be entirely unaffected by the action of the breath, shall be easily attached, detached, and cleaned, if necessary, shall be attractive in appearance and have no detachable parts to get out of order, and which shall not interfere in the slightest degree with the transmission of sound.

In the accompanying drawings, Figure 1 is a front view of the device. Fig. 2 is a rear View, and Fig. 3 is a central sectional view.

A represents the telephone-guard, made entirely of celluloid and from a single piece. It

is circular in shape and fiat in its central portion, but rolled at its outer edge around its entire circumference, the edge of the roll just meeting but not secured to the rear surface of the flat portion. The roll because of its being free from the said rear surface has an elasticity whereby it grips the mouthpiece of the telephone, at the same time permitting it to be removed and replaced with the least possible effort.

1. A telephone-guard molded or formed of one piece of celluloid and provided with a curled flange to removably hold it in place, substantially as described.

2. A guard for telephone-mouthpieces con= sisting of a thin disk of celluloid having its circumferential edge formed into an annular roll, substantially as described.

3. A guard for telephone-mouthpieces consisting of a thin disk of celluloid having its circumferential edge formed into an annular roll, the edge meeting, but not secured to, the rear surface of the disk whereby a smooth front surface and an elastic gripping-ring are provided, substantially as described.
